If you are describing a circuit breaker then its electromagnetic trip component will operate in the event of a line*-to-ground (*not 'phase'!) short circuit. The thermal overload component will only operate in the event of a sustained overload.
The term, 'overcurrent', describes either an 'overload current' or a 'short-circuit current'.An 'overload current' is a current that is higher than a circuit's 'rated current'. For example, if you have too many loads plugged into the same circuit, then the resulting current is an 'overload current'.A 'short-circuit current' is a large current resulting when a line ('hot') conductor accidentally makes contact with either a neutral conductor or an earth (ground) conductor.
There is a heated bimetallic strip that provides a time delay small overload protection. When its contact makes, it energizes a coil to trip the breaker. Some breakers are mechanical, though. There is a coil that trips the breaker instantly on large overload.
An LSIG air circuit breaker (ACB) operates by using air as the insulating medium and relies on electromagnetic and thermal mechanisms to protect electrical circuits. It features a trip unit that monitors current and detects overloads, short circuits, and ground faults. When an abnormal condition is sensed, the breaker trips by opening the contacts, thereby interrupting the current flow. The LSIG designation indicates its capability to provide protection against overload (L), short circuit (S), ground fault (I), and earth fault (G) conditions.
1. direct ground circuit 2. virtually ground circuit
If you ground the flow of current like the last part of your question states you will not have a complete circuit as the circuit will open on a short circuit. To make a complete circuit operate you need a power source, an overload device to protect the conductors of the circuit, conductors to carry the current and a load across the power source which causes the current to flow in the circuit. Leave any one of these things out and you will not have a complete circuit.
There is an overload or short to ground in the circuit.There is an overload or short to ground in the circuit.
Short to ground or overload in the circuit.Short to ground or overload in the circuit.
Circuit overload?Dead short to ground?
The circuit trip in your electrical system could be caused by an overload of electrical devices on the circuit, a short circuit, or a ground fault.
AN over-current situation. Could be a short to ground, or a circuit overload.
Too much current flow in the circuit. Overload or short to ground.
Fuses, Circuit Breakers, GFCI (Ground Fault Circuit Interrupter), Surge Protector, etc.
Circuit breakers trip when there is an overload of electrical current flowing through the circuit, which can happen due to too many devices being plugged in, a short circuit, or a ground fault.

A circuit breaker trips when there is an overload of electrical current flowing through the circuit, a short circuit, or a ground fault. This causes the circuit breaker to automatically shut off to prevent damage or fire.
Circuit breakers trip when there is an overload of electrical current, a short circuit, or a ground fault in the electrical system. These factors can cause the circuit breaker to automatically shut off to prevent damage or fire.
Your circuit breaker may be tripping due to an overload of electrical current, a short circuit, or a ground fault in your electrical system. It is important to identify and address the underlying issue to prevent potential electrical hazards.
